+Vhost PMD xstats test plan
+==================================
+
+This test plan will cover the basic vhost pmd xstats case and will be worked as a regression test plan. In the test plan, we will use vhost as a pmd port in testpmd.
+
+Test Case1: Vhsot PMD xstats based on packet size
+======================================================================
+
+flow:
+TG-->NIC-->>Vhost TX-->Virtio RX-->Virtio TX-->Vhsot RX-->NIC-->TG
+
+1. Launch testpmd by below command, bind one physical port to igb_uio, then launch the testpmd
+ rm -rf vhost-net*
+ ./x86_64-native-linuxapp-gcc/app/testpmd -c 0x30 -n 4 --socket-mem 1024,0 --vdev 'net_vhost0,iface=vhost-net,queues=1' -- -i --nb-cores=1
+ testpmd>
+
+ ssh 10.240.176.254 -p 6087
+
+2. Launch VM1,
+
+ taskset -c 6-7 \
+ /root/qemu-versions/qemu-2.5.0/x86_64-softmmu/qemu-system-x86_64 -name us-vhost-vm1 \
+ -cpu host -enable-kvm -m 2048 -object memory-backend-file,id=mem,size=2048M,mem-path=/mnt/huge,share=on -numa node,memdev=mem -mem-prealloc \
+ -smp cores=2,sockets=1 -drive file=/home/osimg/ubuntu16.img \
+ -chardev socket,id=char0,path=./vhost-net \
+ -netdev type=vhost-user,id=mynet1,chardev=char0,vhostforce,queues=1 \
+ -device virtio-net-pci,mac=52:54:00:00:00:01,netdev=mynet1,mrg_rxbuf=off,mq=on \
+ -netdev tap,id=ipvm1,ifname=tap3,script=/etc/qemu-ifup -device rtl8139,netdev=ipvm1,id=net0,mac=00:00:00:00:10:01 -localtime -vnc :10 -daemonize
+
+
+3. On VM1, ensure the same dpdk folder is copied and run testpmd, use txqflags=0xf01 ::
+ ./x86_64-native-linuxapp-gcc/app/testpmd -c 0x3 -n 4 -- -i --txqflags=0xf01
+ testpmd>start
+
+4. On host, testpmd, set ports to the mac forward mode
+
+ testpmd>set fwd mac
+ testpmd>start tx_first
+
+5. On VM, testpmd, set port to the mac forward mode
+
+ testpmd>set fwd mac
+ testpmd>start
+
+6. On host run "show port xstats all" at least twice to check the packets number
+
+ testpmd>show port xstats all
+ rx_q0_size_64_packets: 16861577
+ rx_q0_size_65_to_127_packets: 0
+ rx_q0_size_128_to_255_packets: 0
+ rx_q0_size_256_to_511_packets: 0
+ rx_q0_size_512_to_1023_packets: 0
+ rx_q0_size_1024_to_1522_packets: 0
+ rx_q0_size_1523_to_max_packets: 0
+
+
+7. Let TG generate different size of packets, send 10000 packets for each packet sizes(64,128,255, 512, 1024, 1523), check the statistic number is correct
+
+
+
+Test Case2: Vhsot PMD xstats based on packet types
+======================================================
+
+Similar as Test Case1, all steps are similar except step6,7:
+
+5. On host run "show port xstats all" at least twice to check the packets type:
+
+ testpmd>show port xstats all
+ rx_q0_broadcast_packets: 0
+ rx_q0_multicast_packets: 0
+ rx_q0_ucast_packets: 45484904
+
+
+
+6. Let TG generate different type of packets, broadcast, multicast, ucast, check the statistic number is correct
+
+
+Test Case3: Performance compare with xstats turn on/off with vector path(Mergeable on and txflags=0xf01)
+======================================================
+
+1. Launch testpmd by below command, don't bind NIC to igb_uio, then launch the testpmd
+ rm -rf vhost-net*
+ ./x86_64-native-linuxapp-gcc/app/testpmd -c 0x30 -n 4 --socket-mem 1024,0 --vdev 'eth_vhost0,iface=vhost-net,queues=1' -- -i --nb-cores=1
+ testpmd>
+
+2. Launch VM1, mrg_off=off so to enable the mergeable::
+
+ taskset -c 6-7 \
+ /root/qemu-versions/qemu-2.5.0/x86_64-softmmu/qemu-system-x86_64 -name us-vhost-vm1 \

+
+
+3. On VM1, ensure the same dpdk folder is copied and run testpmd, use txqflags=0xf01 ::
+ ./x86_64-native-linuxapp-gcc/app/testpmd -c 0x3 -n 4 -- -i --txqflags=0xf01
+ testpmd>start
+
+4. On host, testpmd, set ports to the mac forward mode
+
+ testpmd>set fwd io retry
+ testpmd>start tx_first 8
+
+5. On VM, testpmd, set port to the mac forward mode
+
+ testpmd>start
+
+6. testpmd>show port stats all
+ xxxxxxx
+ Throughput (since last show)
+ RX-pps: xxx
+ TX-pps: xxx
+
+7. The performance drop after turn on xstats should under 5%
+
+

+
+1. Launch testpmd by below command, don't bind NIC to igb_uio, then launch the testpmd
